Piperacillin/tazobactam or temocillin

Assistance Publique - Hôpitaux de Paris · Phase 3 active Small molecule

Piperacillin/tazobactam and temocillin are beta-lactam antibiotics that inhibit bacterial cell wall synthesis by binding to penicillin-binding proteins, with tazobactam providing beta-lactamase inhibition to overcome resistance.

Piperacillin/tazobactam and temocillin are beta-lactam antibiotics that inhibit bacterial cell wall synthesis by binding to penicillin-binding proteins, with tazobactam providing beta-lactamase inhibition to overcome resistance. Used for Serious gram-negative and gram-positive bacterial infections (piperacillin/tazobactam), Aerobic gram-negative infections including Enterobacteriaceae (temocillin), Hospital-acquired and nosocomial infections.

Mechanism of action

Piperacillin is an extended-spectrum penicillin that disrupts peptidoglycan cross-linking in bacterial cell walls, while tazobactam is a beta-lactamase inhibitor that protects piperacillin from enzymatic degradation by resistant organisms. Temocillin is a beta-methoxy-substituted penicillin with intrinsic resistance to many beta-lactamases. These agents are used to treat serious gram-negative and gram-positive bacterial infections.
